Calcrete aquifers in the arid Yilgarn region of central Western Australia are a biodiversity hotspot for stygofauna. A distinct pattern of interspecific size class variation among subterranean dytiscid beetle species has been observed in 29 of these aquifers where either two or three small, medium and/or large sympatric species are found that are in some cases sister species. We used a 3.5 km2 grid of bores to sample dytiscids on a fine‐scale and employed a comparative phylogeographical and… 

Patterns of population genetic variation in sympatric chiltoniid amphipods within a calcrete aquifer reveal a dynamic subterranean environment

It is proposed that isolation of populations in refugia within the calcrete, followed by expansion events, as the most likely source of intraspecific genetic diversity, due to changes in water level influencing gene flow across the cal concrete.

Evidence for population fragmentation within a subterranean aquatic habitat in the Western Australian desert

Findings suggest that microallopatric speciation within calcretes may be a significant diversifying force, although the proportion of stygofauna species that may have resulted from in situ speciation in this system remains to be determined.

Deep phylogeographic structuring of populations of the trapdoor spider Moggridgea tingle (Migidae) from southwestern Australia: evidence for long‐term refugia within refugia

The hypothesis that climate change, particularly the aridification of Australia after the late Miocene, and the topography of the landscape, which allowed persistence of moist habitats, have been major drivers of speciation in southwestern Australia is supported.

Species diversity and genetic differentiation of stygofauna (Syncarida : Bathynellacea) across an alluvial aquifer in north-eastern Australia

The initial results of a stygofaunal survey of the Burdekin River alluvial aquifer in Queensland, and surveys of bathynellaceans in several otherAlluvial systems in south-eastern Australia, suggests that groundwater ecosystems of eastern Australia may contain high styg ofaunal diversity by Australian and world standards, particularly at the generic level for parabathynellids.

Biogeographic history of subterranean isopods from groundwater calcrete islands in Western Australia

The role of late/post‐Miocene aridification as a key driver of the evolution of subterranean invertebrates in the calcrete islands of Western Australia is confirmed, supporting the climatic relict hypothesis.

Extreme genetic diversity among springtails (Collembola) in subterranean calcretes of arid Australia.

The subterranean islands hypothesis for calcretes of the Yilgarn region in Western Australia applies to many stygobitic (subterranean-aquatic) species that are "trapped" evolutionarily within

Evidence for speciation underground in diving beetles (Dytiscidae) from a subterranean archipelago

This study represents one of the first confirmed cases of subterranean speciation in cave insects and the assessment of genes undergoing pseudogenization provides a novel way of testing modes of speciation and the history of diversification in blind cave animals.

Molecular phylogenetic analyses reveal a new southern hemisphere oniscidean family (Crustacea : Isopoda) with a unique water transport system

This study presents phylogenetic analyses using 28S-only and combined 18S, 28S rDNA and mitochondrial cytochrome c oxidase subunit I (COI) data, and presents results for a detailed morphological study of the antennae and other cephalic structures of exemplar taxa.

The first complete mitochondrial genomes of subterranean dytiscid diving beetles (Limbodessus and Paroster) from calcrete aquifers of Western Australia

The first whole mt genomes from four subterranean dytiscid beetle species of the genera Limbodessus, L. palmulaoides, Paroster and Paroster are presented and provide a basis for future investigations of adaptive evolutionary changes that may occur in mt genes when species move underground.

Evolution of Blind Beetles in Isolated Aquifers: A Test of Alternative Modes of Speciation

It is shown that it is very unlikely that the high number of sympatrically occurring sister species can be explained by a combination of allopatric evolution and repeated colonisations alone, and diversification has occurred within the aquifers and likely involved sympatric, parapatric and/or microallopatrics speciation.




It is concluded that individual calcrete aquifers were colonized by several distantly related diving beetle lineages, indicating that all evolutionary transitions took place during the Late Miocene and Early Pliocene as a result of aridification.

Subterranean archipelago: mitochondrial DNA phylogeography of stygobitic isopods (Oniscidea:Haloniscus ) from the Yilgarn region of Western Australia

Comparative phylogeographic data from dytiscid beetles and amphipods provide strong support for the ‘subterranean island’ hypothesis, applying to both air-breathing and fully aquatic arthropod groups.

Subterranean archipelago in the Australian arid zone: mitochondrial DNA phylogeography of amphipods from central Western Australia

Phylogenetic analyses and population genetic analyses provided strong evidence for the existence of at least 16 crangonyctoid and six hyalid divergent mitochondrial lineages, each restricted in their distribution to a single calcrete aquifer, in support of the ‘subterranean island (archipelago) hypothesis’ and extending its scope to include entirely water respiring invertebrates.

DNA barcoding of stygofauna uncovers cryptic amphipod diversity in a calcrete aquifer in Western Australia’s arid zone

The results show that the aquifer contains at least 12 macro‐invertebrate species and DNA barcoding provides a useful means for discriminating species in this system.

Cryptic speciation in two widespread subterranean amphipod genera reflects historical drainage patterns in an ancient landscape

Molecular data used to examine the roles of drainage patterns in structuring genetic diversity in Pilbarus and Chydaekata suggests cryptic speciation has occurred, and similar phylogenetic signals in both taxa imply similar evolutionary histories.

Islands under the desert: molecular systematics and evolutionary origins of stygobitic water beetles (Coleoptera : Dytiscidae) from central Western Australia

The analyses indicate that there have been multiple independent origins of stygobitic dytiscids and that origins correlate with the onset of aridity during the Miocene and also provide evidence that each calcrete aquifer may represent a 'subterranean island'.

Genetic diversity and evolutionary relationships of the troglodytic ‘living fossil’Congeria kusceri (Bivalvia: Dreissenidae)

DNA sequences from two mitochondrial genes are used to compare levels of genetic variability and to test phylogenetic relationships of C. kusceri with surface‐dwelling dreissenid relatives and reveal that Mytilopsis is the sister genus to Congeria and this clade forms the sister taxon to Dreissena.

A deep phylogeographical structure is revealed in the salt water rotifer Brachionus plicatilis, with a division into two main lineages with distinct geographical distributions, which probably diverged at the beginning of the Pleistocene period.

Gene flow and population history in high dispersal marine invertebrates: mitochondrial DNA analysis of Holothuria nobilis (Echinodermata: Holothuroidea) populations from the Indo‐Pacific

The population genetic structures detected are likely to be formed prior to the last ice age, with some indications for high dispersal on shorter time scales and may correspond to a late Pleistocene population expansion inferred from haplotype mismatch distributions.

Systematics and evolution of the Australian subterranean hydroporine diving beetles (Dytiscidae), with notes on Carabhydrus

It is shown that pre-adaptations such as preference for temporary, but seasonally reliable, water and preference to live among gravel and sand along running water would have favoured transitions from surface to stygobitic life, but that large body size may have restricted the likelihood of successful transitions.
